OMAPL138 DMA

Other Parts Discussed in Thread: OMAPL138

i try to set up the OMAPL138, use the DMA to read ADC value from MCBSP1. 

as I checked the memory,  I can see data from DRR  *(unsigned int *)0x01D11000, but InputAdc0 is always 0. 

Can anyone help to advise? Thanks in advance, 

paramSet.srcAddr = (unsigned int)DRR;
paramSet.destAddr = (unsigned int)&InputAdc0;
